This is a preliminary design of a variable power supply I might develop. All ideas and comments are welcome.

Please post its schematic and parts list.

I changed the opamp load resistor from 100K to 200K. But of course the voltage regulation is no where near as good as the 30V Stabilized Power Supply.

The output of an opamp is class-AB push-pull so it does not need a load resistor.
Where is your schematic and parts list?
